Abstract

Ein Zugmittelgetriebe für ein Arbeitsgerät, insbesondere für einen an ein Fahrzeug anschließbaren Rasenmäher, ist mit wenigstens einem endlosen Zugmittel (22) zum Antrieb mindestens eines Arbeitswerkzeugs, einer Antriebsriemenscheibe (24) und mit mindestens einer jeweils einem Arbeitswerkzeug zugeordneten Riemenscheibe (18) versehen. Das Zugmittel erhält seine Vorspannung über eine Spannscheibe (28), die an einem Spannarm (32) vorgesehen ist, der derart schwenkbar gelagert ist, dass er in eine erste Richtung, in der das Zugmittel (22) spannbar ist, und in eine zweite Richtung verschwenkbar ist, in der das Zugmittel (22) entspannbar ist. Die Bewegung des Spannarms (32) in die zweite Richtung wird über eine einstellbare Druckfeder (42), die im normalen Einsatz zusammengedrückt ist und deren Rückstellkraft in die erste Richtung wirkt, blockiert.
